Definitions

  • the invention relates to an apparatus as disclosed in the preamble part of claim 1.
  • a weaving machine and its yarn feeders represent a large number of functions which have to be individually controlled and supervised and have to be mutually inter-related to achieve an optimum function of the weaving machine.
  • the controlling system must work rapidly and functionally reliably with short reaction times.
  • a computerized system allows to store a large amount of information for the control and the supervision. Signal-processing units, transmitters and drive units can be used.
  • Message transmission in the computerized system must take place accurately and with such speed that events which have occurred are detected sufficiently rapidly in the places where the events which have occurred are to be acted upon. For each transmission a sequence of actions is to be carried out. This sequence must be synchronized, which can be achieved with trigger signals which gives rise to a certain sequence being carried out in the system, and, acknowledgement signals which issue acknowledgement that an effected sequence is performed. An acknowledgement signal can be such that it directly initiates a new run.
  • actions e.g. activations and stops, are to be prepared in advance so that sudden accelerations and decelerations are avoided or high speeds can be avoided.
  • control element in the apparatus according to the invention on the basis of the programmed or stored weaving pattern or parts of the weaving pattern the control element ascertains the up-coming yarn winding-on requirement.
  • a control action from the control element proceeds in advance to the function control unit of the feeder, before yarn consumption actually starts, in order to prevent acceleration, speed or deceleration of the yarn from exceeding said predetermined value.
  • the function control units of the feeders comprise communication control parts with connection interfaces to a communication connection (a data bus) and microcomputers for control or supervision of the functions of the feeder.
  • a serial bit flow effected by the communication control parts or the units at the serial connection proceeds in the form of messages which comprise a frame and data part. Said frames comprise bits which are divided up for the transmission and reception functions of the system.
  • the function control units or the communication control parts can be responsive to predetermined markings or addresses in said messages. In the event of a message intended for a selected feeder, this receives and stores the message for action depending upon the content of the message.
  • the function control units can also work with a feedback function with transmitters which feedback stepwise or continuously a parameter change caused within the control function, e.g. change in movement, state etc.
  • Informations can be sent from one unit to another or from the control element (the main computer) which is part of the computer system of the weaving machine.
  • Said information can relate to control information or activation information, which in turn selects or intiates stored control information in the unit concerned, e.g. in a second microcomputer.
  • control information the unit effects control actions of the associated feeder
  • the control actions can control the motor of the feeder depending upon a weaving pattern which is programmed in the computer system of the weaving machine.
  • the control action can relate to a control of the motor of the feeder in relation to the motors of other feeders.
  • a system comprising two or more yarn feeders for a textile machine like a weaving machine for weaving a free pattern (Multi-colour weaving).
  • all feeders procure a yarn stock from a yarn supply assigned to each feeder.
  • Said yarn stock permits at every moment a yarn consumption from the feeder which is determined by a weaving pattern and which is representative of the operating case in question and is programmed or stored in a control element assigned to all feeders.
  • the control element On the basis of the programmed or stored weaving pattern, or part of the weaving pattern, the control element ascertains the coming yarn winding-on requirement. This ascertainment can be achieved depending upon possible sensing or measurement of the existing yarn stock on each feeder.
  • a textile machine 1 e.g. a weaving machine like a shuttle machine, or a jet machine, is provided with a supervising computer system 2, by means of which the different functions of the machine are controllable and supervisable.
  • the connections of the system to the machine have been symbolized with 3 and the connections of the machine to the system with 4.
  • Yarn feeders 5, 6, 7 and 8 are connected to the weaving machine 1.
  • the feeders are of known type and are therefore not described in detail. E.g. their yarn supplies have not been shown for sake of clarity.
  • Each feeder has electrical connection parts 5a, 6a, 7a and 8a and a function control unit 9, 10, 11 and 12.
  • the units are preferably located close to or on each feeder.
  • Each unit comprises at least one first micro-computer 13, 14 for serial interface control and serial bit flow processing.
  • Memory circuit 15 RAM, ROM
  • a clock circuit 16 are included.
  • a communication port 17 is provided, via which read-in and read-out elements can be connected via connections 18 for entering and retrieval of information, for programming etc.
  • Each unit is connected to a second micro-computer 19 which effects the action, supervision etc. of the respective feeder. By means of the second micro-computer 19, calculations can be carried out for optimum control and supervision of each feeder via the connection 20.
  • the second micro-computer comprises conventional peripherals such as memory circuits 21, communication circuits 22 etc.
  • the connection interface comprises A/D and D/A circuits, communication terminals, pulse output etc.
  • the second micro-computer 19 can be integrated in the unit 9 or alternatively constitute a separate unit.
  • a further micro-computer 23 can be connected to a separate communication control part 24, communicating via a connection interface 25 for parallel communication.
  • the units 9-12 can be constructed with identical, or essentially identical, connection interfaces so that individual interchangeability exists among the units. Any unit can take the place of another unit, at least after a minor adjustment. In cases where a separate communication control part 24 exists in all units, these can be made individually interchangeable in corresponding manner.
  • Each unit 9-12 is arranged connectably to a two-wire connection 26, 27 for serial communication or message transmission.
  • the system 2 can comprise at least one control computers 28 as a supervising computer or control element for the units 9-12. Two-way or one-way exchanges of information between the control element and the units or between the units is symbolized with arrows 29-38.
  • the connection with the digital connection 26, 27 is made by terminal elements 39.
  • Message exchange can take place with messages of different types.
  • a bit flow between the units or between the units and the control element is arranged in said messages which comprise a frame part and a data part (applies to one type of message).
  • the messages can be executed with markings or addresses intended for the units.
  • Each unit receives and stores its addresses which are assigned in the system. Alternatively, the system can operate with a certain order for the units.
  • the system can work with a start-up phase, in which control information is issued for selection of feeder functions, e.g. depending upon a programmed or selected weaving pattern, and an operation phase in which selected feeder functions are diagnosed, supervised, controlled, and effected.
  • the yarn quantity can be measured, the thread tension supervised etc.
  • FIG. 2 shows a first type of message 40 which consists of a frame part which has the same length L as the message 40.
  • the frame is constructed of a start field 40a, a priority field 40b, a control bit field 40c, a total control field 40d, and acknowledgement and completion fields 40e and 40f.
  • the content of the priority field 40b determines the ranking of the message.
  • Instantaneous signals as trigger signals have highest priority.
  • Normal communication signals have lower priority according to the time requirement.
  • Pick signals, yarn break signals, arrival signals, feeder exchange signal etc. have the highest priorities, while transmission of information regarding the long-term functional working in the textile machine has lower priority.
  • a second message type 41 ( Figure 3) also comprises a data field 41a.
  • the frame part in message 41 consists of the fields 41b and 41c.
  • the data field contains information which is to be transmitted between the units.
  • the communication works bit-synchronously.
  • the messages are assigned relatively short lengths L and L'.
  • L and L' can be selected in the order of magnitude 0.05 - 0.1 ms (at 1 Mbit/sec).
  • Distances a, a' and b respectively are selected with great accuracy. Bit speeds of e.g. 1 Mbit/sec or higher, e.g. 4 Mbit/sec, are utilized.
  • a basic feature of one type of transmission may be that two different types of logic levels are used, namely a dominant level "0" and a non-dominant level "1". By said two levels, prioritization and fault detection are made possible.
  • the hardware in the system is designed so that if one or more transmitters or units transmit a dominant level, this will be received in the communication, irrespective of how many units are transmitting a non-dominant level.
  • the transmission of a bit is effected by means of the transmitted bit being divided up into five parts.
  • the first part is a synchronizing part which normally starts the bit.
  • the second part consists of time increase part, with which the bit is increased in the event of resynchronization.
  • a third part relates to a first delay part which is attributable to a time interval, during which a stable level is obtained. At the end of this time, the value of the bit is read off.
  • the fourth part consists of a second delay part, which forms a time interval in order that the circuit may determine internally whether it is the current unit which is to transmit the coming bit and which bit is to be transmitted in such a case.
  • the fifth part is attributable to a reduction part which can be removed in the event of resynchronization.
  • All units which want to have access to the connection start to transmit their message as soon as there is a free space at the connection.
  • the different messages have different priority. Messages with lower priority are interrupted. The message with the highest priority comes to be completed. All units are adjusted to receive an assigned message and pick it up and, depending upon the message, carry out the function in question or pick up an actual piece of information. Acknowledgement can take place in different ways.
  • a receiving unit can e.g. transmit an acknowledgement bit when it considers it has received a correct message. Another possibility is that the receiving unit answers by means of transmitting a message back depending upon a received message.
  • the receiver can alternatively transmit a special acknowledgement message.
  • a manner of ordering priority is thus that after a completed message, the units receive different delays or waiting times before they can start the transmission.
  • the unit which has the highest priority has a short waiting time and those with low priority have to wait a long time before they can transmit.
  • the waiting time with normal use of the connection with a maximum transmission speed can be 148 ⁇ s (2 x 111 bits) plus the time it takes for the processor to process the information with its program.
  • the minimum transmission time is half of the maximum. By means of only allowing, at sensitive moments, transmission of messages without data, this time can be reduced to 62 ⁇ s. All these calculations are made with a bit frequency of 1.5 Mbit/sec and on the assumption that the transmitted message has the highest priority.
  • Figure 4 shows three units 42, 43 and 44 connected to the connection 26'.
  • the following table shows the priority selection. The construction of the priority field in the message for the respective unit 42-44 can be seen in the table. The message of the unit 44 has most dominant levels and is selected before the messages of the units 42 and 43.
  • Prioritization can take place also in one field of the message with non-dominant and dominant levels and bit spaces.
  • a unit compares the transmitted bit in a bit space with the state received in the communication, the unit notes that a non-dominant bit has been overwritten by a dominant one. The unit interrupts its transmission.
  • a further unit makes the same observation of the difference between the transmitted bit value and that which the unit sees in the communication, for which reason the transmission is interrupted.
  • another unit notes that it had the highest priority since it never had to interrupt its transmission and consequently completes the message.
  • units 42', 43' and 44' are assigned different waiting times ⁇ t, ⁇ t' and ⁇ t'' after collision.
  • the unit 42' which is assigned the longest waiting time ⁇ t'' receives priority at the connection, whereas the other units must thus wait for their respective transmission.
  • the transmitting units In the event of simultaneous starts after a time interval, the transmitting units indicate that their transmission is colliding. When a transmitting unit detects this, it goes into a fault detecting phase in order to complete the message and indicate to other units that the transmission has collided. The completion is carried out in such a manner that all units involved transmit a sequence of dominant bits which overlap one another so that by these means a marked completion of the collision can be detected by all units. From a point in time KA, all units wait a predetermined time. The unit with the highest priority waits the shortest time. The units with lower priority wait longer and, when the time comes at which the latter units are to start to transmit, they indicate that the connection is occupied, for which reason the units concerned have to wait until the communication becomes free.
  • Figure 6 shows that dominant levels are first transmitted in order to make clear that a unit wishes to transmit.
  • the units 42'', 43'' and 44'' are assigned different waiting times vt1, vt2 and vt3 after all units have finished transmitting dominant bits.
  • the unit 44'' with the shortest waiting time vt1 gains priority.
  • the edges of the pulse trains must be kept to the time t1 with great accuracy (e.g. 100 nanosec).
  • the units do not start to transmit any message without starting the sequence which in Figure 5 indicates a collision.
  • a collision is thus signalled irrespective of whether any other unit is transmitting or not.
  • the advantage is that the delay is constant and the collision indication does not need to be carried out. Prioritization takes time even if there is only one unit which is to transmit.
  • Figure 7 shows priority selection for units 42''', 43''' and 44''.
  • the starting point is the number of bits BA, BA' and BA'' or times T1, T2 and T3 respectively in the respective message.
  • the message for the unit 44''' with the greatest number BA'' receives the transmission state.
  • the start sequence is used for prioritization.
  • the length of the start sequence varies.
  • the unit which has the longest start sequence is the last to stop with its start sequence and has highest priority.
  • time TU expires for the unit to clarify that it is itself which is to transmit.
  • the prioritization times T1, T2 and T3 must be so different that they can not be mixed.
  • FIG 8 shows units 45 and 46 of different types.
  • Unit 45 is highly intelligent.
  • Unit 46 is a simpler type.
  • the unit 45 has a microcomputer 47 which is connected to memory areas 48, 49 (RAM or ROM) and works into a connection interface 50 with D/A and A/D converters. Also included are counters, pulse outputs and pulse inputs.
  • the connection interface 50 is provided with a communication terminal 51 and works into an electromechanical part 52 belonging to an element in the textile machine.

  • the weaving machine informs the system of its breadth and working speed.
  • the weaving machine further informs the respective feeder of the coming pick sequence number, e.g. 16, for the machine speeds most closely corresponding to the number.
  • the weaving machine also informs the respective feeder of how much time will expire after the reference signal before the feeder has to release the yarn.
  • the respective feeder prepares itself with this information by forming an optimum yarn stock and adjusting optimum maximum speed.
